Bringing the Cell Image into Focus
Nov 2 2010
Improvements in transmission electron microscope (TEM) technology increase the power of this imaging tool for the study of cell biology.
Finding a Cure for Spinal Cord Injury with On-Demand LIMS
Oct 25 2010
The Miami Project to Cure Paralysis finds an on-demand laboratory information management system (LIMS) helps to accelerate discovery in its HCS projects.
Saving Cells: Image Processing for Improved Viability, Part II: Iterative Deconvolution
3D light microscopy and deconvolution provide a means to investigate 3D structure, providing near-confocal quality images without the temporal requirements or potentially damaging phototoxicity associated with other 3D imaging technologies. This article is Part II in a series regarding viability, resolution improvement, and measurement in fluorescence imaging. Part I focused on spectral unmixing.

Sep 22 2010
This article is Part I of a two-part series regarding viability, resolution improvement, and measurement in fluorescence imaging. Part II will focus on deconvolution.
Production of Recombinant Proteins and Monoclonal Antibodies in Hollow Fiber Bioreactors
Jan 25
While well-understood, robust and convenient, classical batch-style 2-D culture on non-porous supports or 3-D suspension culture in other devices are really not very biologically relevant models. Cell culture conditions can affect the quality of the antibody or protein produced.
Selecting Robots for Use in Drug Discovery and Testing
Dec 6 2010
Drug discovery and testing, with their need for speed, repeatability and verification, are ideally suited to benefit from robot automation. It is therefore not surprising that robots have been at the forefront of automation developments in both these areas.
HP Scalable Network Storage Systems for Life Sciences
Sep 13 2010
Life sciences research today is advancing exponentially, each step bringing us closer to the realization of truly personalized medicine–preventive care and treatments designed specifically for each individual. In the near future, PCPGM healthcare researchers expect to be able to use predictive genetic testing to create custom treatment plans for individuals and deliver dramatic improvements over today’s one-size-fits-all approach. But research capabilities are only part of the equation; current storage and operating capacities must also evolve to accommodate ever-expanding amounts of data before the goal of personalized medicine can be realized.
Step up to the MIQE
Mar 30 2010
Over the years, polymerase chain reaction (PCR) has evolved into a readily automated, high throughput quantitative technology. Real-time quantitative PCR (qPCR) has become the industry standard for the detection and quantification of nucleic acids for multiple application, including quantification of RNA levels. But a lack of consensus among researchers on how to best perform and interpret qPCR experiments presents a major hurdle for advancement of the technology. This problem is exacerbated by insufficient experimental detail in published work, which impedes the ability of others to accurately evaluate or replicate reported results.
Using the Tecan Genesis Workstation to Automate a Cytometric Bead Array (CBA) Immunoassay
Mar 11 2010
The poster describe the process involved in automating a Cytometric Bead Array (CBA) immunoassay developed to measure relative concentrations of serum antibodies against Tetanus (TT), Sperm Whale Myoglobin (SWM) and Keyhole Limpet Hemocyanin (KLH) in KLH-immunized volunteers.
Ensuring Quality in Assays Performed with Automated Liquid Handlers
Feb 2 2010
The focus of this presentation is to highlight the need of ensuring quality in important assays performed with automated liquid handlers. Nearly all assays performed within a laboratory are volume-dependent. In turn, all concentrations of biological and chemical components in these assays, as well as the associated dilution protocols, are volume-dependent. Because analyte concentration is volume-dependent, an assay’s results might be falsely interpreted if liquid handler variability and inaccuracies are unknown or if the system(s) go unchecked for a long period.
Inkjet System for Protein Crystallography
Feb 1 2010
X-ray crystallography is used routinely by scientists to obtain the three dimensional structure of a biological molecule of interest.Such information can be used to determine how a pharmaceutical interacts with a protein target and what changes might improve functionality. However, the crystallization of macromolecules still remains a serious hindrance in structural determination despite impressive advances in screening methods and technologies.
Attention Deficit & Hyperactivity in a Drosophila Memory Mutant
Nov 9 2009
Action selection is modulated by external stimuli either directly or via memory retrieval. In a constantly changing environment, animals have evolved attention-like processes to effectively filter the incoming sensory stream. These attention-like processes, in turn, are modulated by memory. The neurobiological nature of how attention, action selection and memory are inter-connected is unknown. We describe here new phenotypes of the memory mutant radish in the fruit fly Drosophila.

The mPlrp2 and mClps are involved in the hydrolysis of retinyl esters in mouse liver.
Retinyl esters are the major chemical forms of vitamin A stored in the liver, which can be delivered to peripheral tissues for conversion into biologically active forms. The function and regulation of the hepatic genes that are potentially involved in catalyzing...
Rif-mDia1 interaction is involved in filopodium formation independent of Cdc42 and Rac effectors.
Filopodia are cellular protrusions important for axon guidance, embryonic development, and wound healing. The RhoGTPase Cdc42 is the best studied inducer of filopodium formation, and several of its effectors and their interacting partners have been linked to the...
The structure and function of an arabinan-specific alpha-1,2-arabinofuranosidase identified from screening the activities of bacterial GH43 glycoside hydrolases.
Reflecting the diverse chemistry of plant cell walls, microorganisms that degrade these composite structures synthesize an array of glycoside hydrolases. These enzymes are organized into sequence-, mechanism- and structure-based families. Genomic data has shown...
